Abstract

The container with a product reservoir (2) and a dispensing opening (3) further incorporates either a noise generator (5) or a noise damper (13), with the noise generator or the noise damper functionally connected with the dispensing mechanism (4) in such a way that a pleasant/acceptable sound is produced during the product dispensing process.

Description

The invention relates to a container with a reservoir, one Product discharge opening and a device for discharging in the reservoir located product from the product delivery opening.

Containers of this type are well known. Crushable containers, Aerosol containers and containers with a spray pump have a device for Deliver. In the crushable container, this has a deformable one Container wall, with the aerosol container a valve and with the container with Spray pump on the spray pump. The product either arrives directly from Reservoir to an open product delivery opening or via a channel or a stem to a product discharge opening designed as a nozzle. In the area the product delivery opening of an aerosol container or a container Spray pump can also be provided to generate a foam Bring product in foam form. While crushable containers hardly one noticeable noise during the discharge of product, e.g. B. Hair shampoo, dispense, create aerosol containers and containers with Spray pump a typical sound. This is especially true for one Aerosol container with foam generator.

The well-known containers have the disadvantage that the during the Product noise generated only from the technical design of the Container, e.g. B. its product delivery opening, its facility for Discharge, its dimensions (resonances) and its materials depends. Subjectively, this sound can be perceived as good or less good become. A consumer may conclude something that does not sound positive to him Noise falsely and in a negative way on the available Technology of the container and its contents.

The invention is based on the object, subjectively as unpleasant perceived noise on the container during a product delivery avoid, suppress or overlay.  

The problem is solved according to the characterizing part of claim 1. Then there is a sound generator or a silencer on the container provided, and the sound generator or the silencer is functionally connected to the discharge device in order to during the Product delivery to produce a target sound for a product flow.

The invention has the advantage that during a product delivery a Consumer positive noise is generated. That sound can first be determined empirically through customer surveys and then technically be implemented. There is either a sound generator on the container provided a special sound the natural outflow sound overlaid. Or the natural, i.e. H. that without a sound generator or Outflow noise that arises from the silencer becomes wholly or selective damped, so that its disturbing frequencies with regard to their sound intensity are reduced or that these frequencies are eliminated.

The container is an aerosol container or a spray container, being attached to the container a spray channel leading to a nozzle is provided, and the spray channel points, in particular in a curvature of the spray channel, with respect to its inner Wandung a in the mathematical sense, continuous course (claim 2), d. H. a course without an edge, then vortices come in the outflowing Product only with reduced probability. Since vortex producers of are annoying noises, such a more pleasant sound at the Product delivery reached.

At least one sound rib on the spray channel, in particular radially from the Spray channel is aligned away (claim 3), has the advantage that Sound rib can produce tones corresponding to its dimensions. It can several sound ribs can also be provided, the tones of which overlap. By Resonance and standing sound waves can be in the spray channel and the cap surrounding the sound rib determined that it was pleasant Noises are generated.

A spray channel can be surrounded with a sound-absorbing material, in order to reduce the sound level per se, but also by some To dampen frequency ranges particularly strongly (claim 4). In the area of Stems of a spray container or an aerosol container is one of these  Measure particularly useful since there is a lot of turbulence and corresponding sound generation is therefore present.

The spray channel is soundproof, in particular of several layers selectively surround soundproofing material, and contains at least one Layer a foamed or non-foamed material, especially a thermoplastic elastomer (TPE) or a thermoplastic polyurethane (Claim 5), so that existing by the product delivery to itself Noise can be effectively attenuated or selectively attenuated. The TPE plastics Evoprene®, Santoprene®, Vyram® and Hyrtel® can be achieved. Here could Relatively pleasant noises, especially for hairspray and hair foam can be achieved. Hydrocerol is a foaming agent for the TPE plastic suitable.

If there are several layers of sound-absorbing material, some are suitable Layer combinations for an inner layer lying against one another another layer. The inner layer delimits the product delivery channel, e.g. B. the Spray channel or foam channel. The other layer is directly on the outside Inner layer. Good noise results are achieved with the inner layer - Further layer pairings: 0.5-1 mm material not foamed - 1 to 5 mm Foam, 1 mm unfoamed - 1 to 3 mm unfoamed; 0.5 to 5 mm Foam - 1 to 3 mm unfoamed; 1 mm PP (polyporpylene) not foamed - 5 mm foam; 1 mm PP unfoamed - 1 mm unfoamed, as well as at analog combinations of analog materials. Should be several Frequency ranges are influenced, so several layers can be used corresponding properties can be combined.

Good results are also achieved if the outer layer is covered with a film is sealed to the outside. This then corresponds to a closed cell Foam. The function of the film can also be determined by a film-like one Tool wall created, smooth and unfoamed edge layer be exercised. Edge layers occur with TPU foam parts during molding automatically on the tool wall and are between 0.2 and 1.0 mm thick.

Is the silencer a spiral arranged around a spray channel (Claim 6), so a selective, pleasant change in Spray noise reached. Suitable materials for the spiral are those that  a relatively high mechanical loss factor and a relatively low one Have flexural rigidity, such as. B. corrugated cardboard and tissue paper. This Materials are also very inexpensive.

As a device for dispensing is a button on the container The cap acts mechanically on the wall of the spray channel, and the wall also acts mechanically on a stem of the container (claim 7), so when pressing the button to Purpose of the product also the wall and the stem depressed so that the valve of the Container opens and product flows out. The valve can be an aerosol valve. But it can also be part of a spray pump, so by one Depressing the button generates a spray.

Is the material of the spray channel harder or softer than the material of one Sound rib (claim 8), so a noise can only by this Difference in hardness can be changed.

If a stiffening rib is provided on the spray channel (claim 9), then thereby reducing the oscillation frequency of the spray channel.

The harder and stiffer the spray channel is, the more difficult it can be can be made to vibrate by mechanical excitation. It is there irrelevant whether the excitation is permanent or singular. The stiffening through additional ribs also create a larger component surface. Will the The surface of a component is larger, so the vibration energy is distributed this. The total vibrational areas are determined by a Stiffening reduced and the frequency of the vibration increased. Thus the Sound pressure level of a component with this increased surface area less than without stiffening rib. Furthermore, a stiffening rib also provides one Reflector on which vibrations are reflected.

Relatively hard stiffening ribs are used to generate sound in the Frequency range from approx. 4 to 15 KHz. Relatively soft stiffening ribs serve, however, for sound emissions in the frequency range from 1 to approx. 4 KHz. Thus, a sound rib made of a material of different hardness can be compared with the hardness of the spray channel wall, exists, can be used in in another frequency range to emit sound in order to achieve this  To change the sound of a product delivery. A normal hard wall of the spray channel in connection with relatively soft, on the spray channel provided sound or reinforcement ribs consequently leads to a noise, where the lower ones compared to a conventional spray channel noise Tones are amplified. Such a sound is felt to be "full".

Is the sound rib with the inner surface of one on the container attachable cap connected, in particular injection molded thereon (claim 10), so a different sound can be generated than if the sound rib this Connection would not have. The spray channel or any component of the The emitted sound frequencies lead to resonance vibrations of the Sound rib and as a result of the connection, the cap of the sound rib becomes too an analog vibration on the connection. Is the sound rib formed in a meandering manner and only connected to the cap, see above the sound rib delimits a resonance space, particularly sound waves the wall of the flow channel. According to the dimensions The sinuous rib of the sound attenuates certain frequencies. Thereby there is a special sound.

The human ear perceives frequencies around 4 kHz as relative unpleasant. These frequencies can be seen clearly with a spray jet can be reduced if, according to claim 11, the container is an aerosol container or a spray container, on the container a spray channel leading to a nozzle is provided, and the spray channel either one within the spray channel extending channel insert, or the spray channel from several, in particular there are channel arms running parallel to one another. The dispensed product thus flows through relatively narrow duct parts or duct arms, to get through the flow channel and to the nozzle. This will make the Flow laminar. The flow noise is selectively damped, namely in the range around 4 KHz. The modified flow channel also acts as Noise generator, namely for frequencies that are higher than 4 kHz. This are reinforced. So there is a higher tone.

Sufficiently low frequencies are also used positively by consumers assumed, e.g. B. in an aerosol container with a foaming device. On positive product delivery noise is achieved when according to claim 12 Container is an aerosol container or a spray container, one to one on the container Nozzle leading spray channel is provided, and the spray channel as  Noise generator for a frequency range and as a silencer for one higher frequency range has an extension for the spray channel.

If the container is an aerosol container or a spray container, the container is on provided to a nozzle leading spray channel, and is the spray channel of encased a honeycomb structure which has a plurality of honeycombs, and wherein the honeycomb in the direction of the spray channel, in particular radially to Spray channel are aligned (claim 13), then takes place on the spray channel selective change of spray channel noise. The honeycomb structure can e.g. B. be rectangular, hexagonal or round. The honeycombs are on their faces open and hanging together. The sound vibrations from the spray channel go out, overlap in the honeycomb and in the honeycomb walls. Consequently the energy and loudness of the sound waves are reduced. The honeycomb can consist of cellulose. Nomex® Honeycomb. Their relatively rigid material increases the frequencies of the Spray channel noise.

If a sound chip is provided as the sound generator (claim 14), it can generate a sound that is favorable for a product discharge process. This noise can also be such that its frequency spectrum is in Addition with the frequency spectrum of the technical Discharge noise the frequency spectrum and thus the sound of a Target noise results.

If the sound chip is programmable (claim 15), the sound chip can or several program sounds can be entered, which are then for one Sound delivery are available. Several programs that can be selected (Claim 16), can by using the facility for Unsubscribe. So z. B. as a facility two Operating buttons can be provided, the two different programs can start. The selection depends on the position of the facility (Claim 17), so one position and one in another Position the other program can be retrieved. Is by means of a key or an operating button, e.g. B. depending on the actuation path, a low or a achieved higher spray rate, so each spray rate can be adjusted accordingly pleasant, programmed spray sound assigned to the sound chip become. The same applies e.g. B. for two separate buttons or buttons a container to create a fine or heavy spray. The  Soundchip can also be used to make pleasant sounds of the Container by superimposing an identical frequency spectrum reinforce.

Does the sound chip contain at least one language program, especially one Consultant program (claim 18), one can during a product discharge Advice to the customer regarding the product used. A Such advice is particularly useful for more complicated use. Here, each time the device for discharge is actuated Advice information is given so that use by a majority individual information steps is supported.

The container is an aerosol container or a spray container, being attached to the container a spray duct leading to a nozzle is provided, and the spray duct as Noise generator for one frequency range and silencer for one another frequency range has a plurality of individual channels 9), a relatively good product output is achieved by this large number. Certain Turbulence and Occurrence in a Single Spray Channel frequencies corresponding to these are attenuated, whereby a selective noise reduction for this frequency range is achieved. Noises that are typical for a large number of relatively narrow individual channels reinforced. Thus, a changed, relatively pleasant sound with a Delivery of the product in the container generated.

The container is an aerosol container or a spray container, being attached to the container a spray channel leading to a nozzle is provided, and the spray channel points out as a noise generator for a frequency range and silencers for another frequency range a labium (claim 20), is a changed, relatively pleasant sound when the in the container located product can be generated.

A selective sound attenuation or a selective change of the Spraying noise can be done by adjusting beat frequencies can be achieved. It can cover individual areas of the frequency spectrum be picked out and extinguished by one or more sound sources or be influenced.  

This is due to a vibrating inner wall (labium) directly in the spray channel possible. Due to the size and material of the swinging wall, this can be done Spray noise can be affected. The mechanical drive is the same as for a "labium" (technical term - vibration exciter for wind instruments), the aerosol flowing around it is vibrated, or at an "overblowing duct", at the end of which there is a tear-off edge. For The inner wall itself serves as reinforcement an increase in frequency can be achieved.

As with an organ pipe or a recorder, the aerosol flow hits the very sharp edge of the labium. This creates strong turbulence, that make the labium vibrate. A conscious tone is thus generated. This tone can be determined by the length of the double tube, which is the labium surrounds, change (short = higher tone, long = lower tone).

Since the double tube also better absorb the vibrations that occur can result in the following effects: Frequency change, as well as reduction in flow resistance and thus the vortex that occurs, which leads to a further reduction in noise.

Is the container an aerosol container and is on a valve plate of the Aerosol container provided a valve plate damping as a silencer (Claim 22), such a pleasant delivery sound for the Aerosol containers can be reached.

Valve disks are mainly made of aluminum. This is suitable as Valve plate damping a layer of a applied to the valve plate sound-absorbing material, in particular polyurethane paint or Polyurethane foam (claim 23).

The following foamed TPE plastics are specially for insulating the Suitable valve plates: Evoprene®, Santoprene®, Vyram® and Hyrtel®. For this The Hydrocerol® foaming agent is suitable for plastics.

Suitable material composites and composite materials are characterized by this from the fact that the properties of the Connect individual components sensibly even for extreme applications. On Composite material that, in addition to minimizing vibration transmission  additionally high vibration-absorbing properties in a wide range Frequency range, changes the vibration emission extremely. This acoustically highly effective, two-dimensional material composite should oppose conventional materials a lower mass with good at the same time have mechanical properties. This is mainly about one damping and insulation of mechanical vibrations as high as possible of the aerosol spray system. Two physically different layers are combined into a composite material.

A high vibration damping (high vibration absorption) is with porous, that is here specifically foam-like and / or elastomeric Realized materials that have an open-pored structure towards the vibration source (Pore size approx. 0.2 mm). This task takes over z. B. a thermoplastic foam, which by injection molding and simultaneous Foaming of the above materials is made and high Porosity (up to 95%).

As a variation, it is also conceivable that the outer layer is still covered by a film is sealed to the outside. This then corresponds to a closed cell Foam.

So that the absorber can dissipate a lot of vibrational energy, the First penetrate the vibration as free of reflection as possible into the absorber. This with an open-pore, thermoplastic elastomer foam or easily excitable material reached. The vibration wave resistance should increase when changing into the absorber at the interface do not change much to the To minimize vibration reflection. By a gradually increasing internal frictional resistance of the absorber, due to its numerous narrow channels, the back and forth air becomes energy in the form of heat withdrawn and given to the skeletal material of the absorber. This takes the amplitude of the vibration pressure. The one dampened by the absorber Vibration wave hits the insulation layer, where on the one hand it goes back into the Absorber reflects and on the other hand into a body vibration wave is converted. To the vibration radiation in the to be protected To minimize space, the bending shaft in the insulating material must be as strong as possible be dampened. A high mechanical loss factor and a low one Bending stiffness favors the damping of the bending shafts. With Thermoplastic elastomers can have these mechanical properties  be achieved. The more complete the vibration absorption of the incident as well as the reflected vibration wave, the less Vibration energy gets into the insulation layer. The damping Properties of the elastomeric insulation layer result in further minimization the vibration radiation in the space to be protected. The lower the The density of the damping material (foam or lacquer) is the higher influenced frequency.

If the container is an aerosol container with an insert at the outflow end of a spray channel ( 10 ), the insert containing a nozzle, and as a noise damper either the insert consists of an elastic plastic, or the insert is connected to the spray channel by means of an elastic adhesive (claim 23), a pleasant sound is thus achieved during a spraying process. Interfering frequencies are absorbed by the elastic material in the area of the nozzle.

An insert becomes due to the expansion of the aerosol that takes place before the insert excited by a vibration. This vibration is through an elastic insert hardly transferred to the flow channel.

This function can also be performed using a commercially available insert be when this insert with an elastic glue into the flow channel is glued in. However, the layer thickness of the adhesive material must be so great be that hardly any vibrations are transmitted. In general you can assume about 4 mm wall thickness for the adhesive.

Conditional pressure fluctuations occur in the flow channel due to the partial expansion of the aerosol in the flow channel. An elastic These pressure fluctuations will not be inserted or an elastic adhesive transfer.

Is as a sound generator a resonance surface inside a cap of the Provided container (claim 24), so this resonance surface after her Excitation of a sound corresponding to its dimensions. The Soundboard can be a soundboard that cap the room in two divides. The resonance surface can have one or more passages. Either the location and the choice of materials influence the sound. It can too more than two rooms are created or only partitions are provided  to separate areas of space. Between a soundboard and the A silicone seal can also be provided on the inner wall of the cap to reduce transmission of the resonance sound to the cap. Is on the other hand, if the cap is waving for a target sound, then instead a silicone seal the best possible, rigid contact between the Soundboard and the inner wall of the cap, e.g. B. by a Plastic welding, to be provided.

The container is an aerosol container, which is a valve, a valve disk, a Has valve housing and a stem, and in which as a silencer acoustic barrier layer is provided between the valve and the valve plate is (claim 25), is an acoustic decoupling of the valve as Sound source reached by the valve plate as a resonance body. This Decoupling prevents the valve plate from swinging along with that Valve plate connected components, such as. B. the container jacket with the valve. Such a measure is very effective since it is at the valve noise source starts. The valve itself can remain unchanged. Suitable as a barrier layer a very elastic plastic, such as B. Evoprene®, its thickness is preferably between 0.5 and 8 mm.

Is part of the barrier layer as a seal between the valve housing and the Stem provided (claim 26), this part fulfills the otherwise by separate seal function to perform a seal between the Valve body and stem. The use of this part is less expensive than the use of a separate seal and also acoustically decouples that Valve housing from the actual valve.

If the container is an aerosol container or a spray container, is as a facility to discharge a button of a cap that can be placed on the container provided, and is an acoustic between the button and the cap Sealing provided (claim 27), so this is done Noise reduction through acoustic sealing of the cap. The seal can be done by two sealing lips, one sealing lip on the cap and the other sealing lip is provided on the button (claim 28), or Sealing is achieved through an elastic connection between the button and the edge region of the cap adjoining the edge of the key (Claim 29).  

State of the art is to close the valve stem with a cap by a button press to promote product mass. The well-known keys show but also a more or less large gap to the surrounding cap towards. If this gap is now closed, the vibrating ones change Air mass in the cap and the vibration of the cap. So you get a changed spray noise. The button must still be able to move stay. There are several ways to achieve this, e.g. B .:

Possibility Number 1

The actuator button is pressed using the two-component injection molding process a very flexible plastic connected to the spraycap. The Spraycap is therefore in one piece and has no gap between the button and the spraycap. In this gap there is an extremely flexible Plastic.

Possibility 2

At the transition surfaces between the cap and the button pointed, downwardly curved sealing lips attached, e.g. B. by Two-component injection molding. The two are in the unactuated state Sealing lips next to each other and seal completely. Now on the If the button is pressed, the sealing lip of the button slides down and opens the valve. At the same time, the way down for the top of the Key sealing lip more space because it wants to move outwards. As a result, the gap between the cap and the button is always closed and the interior of the cap is acoustically sealed.

If, as a noise generator for one frequency range and a noise damper for another frequency range, a perforated disc is provided in a stem, which has a plurality of channels, and which is preferably latched into the stem ( 11 ) by means of a latching element (claim 30), this results in a Flow calming on the one hand and local production of a laminar flow on the other hand achieved. Both result in individual frequency ranges being amplified and other frequency ranges being damped. Overall, there is a change in sound, which is perceived as pleasant.

The perforated disc only has channels on one side, with a cover that is preferably designed semi-disc-shaped, the anti-rotation lock  having perforated disc partially covers, and the cover over a in the Stem pipe piece used, which preferably has a stop, and which is connected to a product discharge opening of the container, is rotatable relative to the perforated disc (claim 31), so a consumer by rotating the part containing the product discharge opening itself determine whether he has the product dispensing behavior and related Would like to have noise, which occurs in a certain twisting situation results. So he can z. B. between use of the channels and use choose a passage in the other half of the perforated disc. The stop serves as an orientation for a specific rotational position of the Cover relative to the perforated disc.

Is as a noise generator in a flow channel of an aerosol container inserted sound lip provided, which with the lower part of a Valve housing is connected (claim 32), so by product delivery a certain tone can be generated. The sound lip is from the outflowing Product vibrates. By connecting with the Valve housing can easily the sound lip together with the Valve housing can be manufactured. In the proposed arrangement of the Sound lip on the lower part of the valve housing, the product is liquid, so that there is no gluing and thus a limitation of the Function of the sound lip can come. A serves as a discharge device Spray head of the aerosol container, which is pressed down to a Open valve. The product flows around the sound lip and through the valve to the outside and creates a pleasant feeling on the sound lip Sounded during product delivery.

The sound lip can be aligned in the direction of the flow channel (Claim 33). The outflowing product is relatively large Flow cross-section available, so that the outflow quasi not being affected. In contrast, two sound lips are provided, which are vertical aligned with the direction of the flow channel and in such a way that they form a gap between them (claim 34), a relative intense tone can be produced. Here the sound lips can also overlap (claim 35), which lead to an even higher sound intensity can.  

When dispensing product from a spray container or A very special whistling sound can be generated in aerosol containers, if analog Claim 36 in the direction of flow in front of the sound lip a passage Locking element is provided, and an edge of the sound lip with the Passage forms a labial pipe. This pipe is formed by the fact that the edge is relatively close to the culvert. By changing the Gap width of the passage or the distance of the edge to the passage can the frequency of the sound to be generated is changed. The sound becomes like this hired that it was used by a consumer during a product sale is felt pleasant.

Are several as the silencer and as a sound generator Grooves delimiting the flow channel and extending in the flow direction provided, which preferably by recesses in an extension of a valve housing of a valve are formed (claim 37), so can the turbulence in this area of the flow channel is reduced. By eliminating this turbulence, the frequencies are attenuated generated by this turbulence of the outflowing product. At the same time, the grooves produce a different tone. This frequency change is perceived as relatively pleasant. The corresponding sound is through the Length, width and depth of the grooves influenced, as well as by the number of Grooves.

Is on at the same time as a sound generator and as a silencer funnel-shaped loudspeaker provided, which is designed as a nozzle Product discharge opening of the container connects, and away from the nozzle considered, has an increasing diameter (claim 38), so analogous to the sound of a speech bag during a product delivery changed and reinforced at the same time. The spray cone emanating from the nozzle has enough free space in the funnel.

Is a sound rib provided as a sound generator, which on the one hand with an attachment placed on a stem of an aerosol-filled container is connected, and on the other hand rests against an edge of the container (claim 39), one is dependent on the width and length of the sound rib To achieve sound. The vibration of the attachment is transferred to the Sound rib, which at the end transmits this vibration to the edge. The sound is perceived as pleasant. Is also the edge of the container  interfering tear-off ring provided, which with a line of weakness the sound rib is connected (claim 40), the essay can very first securely connected to the container. Before it is used, the The tear-off ring is separated to release the sound rib in this way.

Is a flow loop in the form of a channel as a noise generator a valve body of a valve of the container provided (claim 41), so an additional noise is generated directly in the valve. That sound is relatively intense in that the valve is the largest noise generator, especially with an aerosol container. The channel is of a relatively small size Part of the outflowing product flows through.

If the container is an aerosol container, a riser pipe leading to a valve has, the riser as a sound generator an extension has, and the extension on the bottom wall or the side wall of the Container rests (claim 42), so the flow noise of the aerosol reinforced in the riser on the one hand in the extension. On the other hand, this becomes Transmitted amplified noise on a container wall, so that this as Resonator is used. The sound achieved is therefore of the dimensions of the Depends on the walls and results in a relative, especially with aluminum cans pleasant sound during product delivery.

If the container is an aerosol container, the side wall or bottom wall as Sound generator alternately a larger and a smaller wall thickness has (claim 43), this wall causes during a product delivery a changed sound. According to the difference in strength and the Dimensions of the larger wall thickness can be perceived as pleasant Aerosol delivery noise can be achieved.

A container designed as an aerosol container containing a to a valve has leading riser pipe, the bottom wall of the container alternately having smaller and larger wall thicknesses as a sound generator.

In a container 1 having a reservoir 2, a product dispensing opening 3 and a device 4 for discharging the reservoir 2 befindlichem product from the product dispensing opening 3, to the container 1, a sound generator 5 and a noise damper 13 is provided (Fig. 1, Fig. 2). The sound generator 5 and the noise damper 13 are functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container 1 serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge 8 of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem 11 of the container 1 . The container 1 is an aerosol container. The spray channel 10 leading to a nozzle 12 is provided in its cap 7 . As a noise damper 13 , better than a technique for preventing excessive noise generation, the spray channel 10 , in particular in a curve 14 of the spray channel 10 , has a continuous course in the mathematical sense on its inner wall 15 .

On spray channel 10, four sound ribs 16 are provided which are oriented radially away from the spray conduit 10 degrees. The sound ribs 16 each form an angle of 90 degrees to one another. If the button 6 is actuated, the spray channel 10 together with the stem 11 is pressed down and a valve (not shown) in the container 1 is actuated. The aerosol exiting through the stem 11 flows through the spray channel 10 and is sprayed out of the nozzle 12 . Due to the action of the noise damper 13 and the noise generator 5 , a relatively quiet noise, which is felt as very pleasant due to the resonances in the cap 7 , is generated when the device 4 is actuated.

In the exemplary embodiment of FIGS. 3 and 4, a cap 7 is provided for fitting onto a container containing an aerosol. The cap 7 has a spray channel 10 which is to receive a stem of the container with a recess 9 . The spray channel 10 is surrounded by a foamed material 17 and thus selectively soundproofed. The material 17 consists of a thermoplastic elastomer based on polypropylene. The spray channel 10 can be pivoted downward by means of a button 6 , so that it opens a valve on the stem of the container, and product is discharged from the nozzle 12 .

In the embodiment of Fig. 5, a spray conduit 12 provided with a nozzle 10 is surrounded by three layers 19 of sound-absorbing material selectively. The inner layer 19 delimiting the spray channel 10 consists of a non-foamed material 18 . This is followed by a foamed material 17 . The latter is covered on the outside by an unfoamed material 18 , a film 19 . All materials 17 , 18 are made of plastic. The selective sound insulation is improved by the layer transitions. Interfering frequencies in the range around 1 kHz and 5 kHz are damped in this way. The material 17 , 18 can be polypropylene.

In the embodiment of FIGS. 6 and 7, a button 6 of a cap 7 which can be placed on a container 1 is provided as the device 4 for discharging. The button 6 acts mechanically on the wall 15 of the spray channel 10 . The wall 15 in turn acts mechanically on a stem 11 of the container 1 . When the button 6 is pressed down, a valve (not shown) located below the stem 11 is opened such that product is sprayed out through the spray channel 10 and a nozzle 12 . A spiral 20 arranged around the spray channel is provided as the noise damper 13 . The spiral 20 consists of corrugated cardboard. The spiral 20 dampens the spray noise so selectively that it is felt to be comparatively pleasant.

In the embodiment of FIGS . 8 and 9, a spray channel 10 is used to discharge product from an aerosol container. The spraying process is started by manually pressing a button 6 on the container. A nozzle 12 is provided as the product discharge opening 3 . On the spray channel 10 , four ribs are provided as noise generators 5 , which serve simultaneously as sound ribs 16 and as stiffening ribs 21 . The wall 15 of the spray channel 10 is stiffened in this way. The wall 15 consists of a relatively hard, non-foamed material 18 , whereas the ribs consist of a relatively soft, foamed material 17 . The material is polypropylene. The ribs amplify the deeper tones of product delivery noise, which is felt to be relatively pleasant.

In the embodiment of FIGS. 10 and 11, a spray conduit 10 serves the discharge of product from an aerosol container. The spraying process is started by manually pressing an actuation button 7 of the container 1 . A nozzle 12 is provided as the product discharge opening 3 . A meandering rib, which serves as a sound rib 16 and as a resonator, is provided on the spray channel 10 as the noise generator 5 and selective noise damper 18 . The wall 15 of the spray channel 10 consists of a relatively hard, non-foamed material 18 , whereas the ribs consist of a relatively soft, non-foamed material 17 . The material is polypropylene. The ribs amplify a few tones of the product delivery noise, which is perceived as relatively pleasant. The cap 7 of the container 1 also contributes to the sound image since the sound vibrations of the sound rib 16 are transmitted to the cap 7 via the connections 22 . The sound is determined by half the length of the part 23 of the sound rib 16 arranged between two adjacent connections.

In the exemplary embodiment in FIGS . 12 and 13, the spray channel 10 is provided with a channel insert 24 running inside the spray channel. If the button 6 is pressed down as a device 4 for discharge, the wall 15 of the spray channel 10 presses on the recess 9 with its wall 15 on the stem 11 . The product then flowing out of the reservoir 2 arrives along the channel insert 24 to the product discharge opening 3 . Since the flow channel 10 is narrowed by the channel insert 24 , the flow has a more laminar effect and there is an increase in frequency in the sound image of the product delivery noise. The channel insert 24 acts as a noise damper 13 for frequencies around 4 KHz, but as a noise generator 5 for higher frequencies. In the embodiment of Fig. 14 this is the same. Here, the spray channel 10 is formed from two channel arms 25 running parallel to one another. The two relatively small cross sections of the channel arms 25 reduce turbulence, which emit frequencies around 4 KHz.

In the embodiment of FIG. 15, a button 6 of a cap 7 that can be placed on a container 1 is provided as the device 4 for discharging. The button 6 acts mechanically on the wall 15 of the spray channel 10 . The wall 15 in turn acts mechanically on a stem 11 of the container 1 . When the button 6 is pressed down, a valve (not shown) located below the stem 11 is opened such that product is sprayed out through the spray channel 10 and a nozzle 12 . An extension 26 for the spray channel 10 serves as a noise damper 13 for higher frequencies and as a noise generator 5 for lower frequencies. The wall 15 of the spray channel 10 together with the extension 26 is relatively long, as a result of which low frequencies with a correspondingly long wavelength are preferred. There is a frequency shift compared to a spray channel 10 of normal length, i.e. without extension 26 . In an analogous manner, a shortening of the spray channel 10 could result in a frequency shift towards higher frequencies.

In the embodiment of FIGS. 16 and 17 of the spray conduit 10 is enclosed by a honeycomb structure 29 having a plurality of honeycomb 27 and the honeycomb 27 are oriented away radially to the spray channel 10 in the direction from the spray conduit 10. The honeycomb structure is rectangular. The honeycombs 27 are open and, because of the relatively high rigidity of the honeycomb walls 28, increase the frequencies of the spray channel noise. The honeycomb structure 29 thus acts as a noise generator 5 for higher frequencies and as a noise damper 13 for lower frequencies.

In the embodiment of FIG. 18, a button 6 is provided in a cap 7 for a container as the device 4 for discharging. The cap 7 can be plugged onto an upper edge of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem of the container 1 . The container 1 is an aerosol container. The spray channel 10 leading to a nozzle is provided in the cap 7 . Two switching elements 31 , 32 are attached to the spray channel 10 . In the starting position of the button 6 shown in FIG. 18, a rounded element 24 of the button 6 is located above the one switching element 31 . If the button 6 is pressed down somewhat, only the switching element 31 is actuated, as a result of which a certain, programmed sound is generated by a sound chip 30 . The sound chip 30 is powered by a battery 33 . After the button 6 is further depressed, the rounded element 34 moves away from the switching element 31 and onto the second switching element 32 , as a result of which the first sound is switched off and the second sound is switched on. Instead of the second sound, product information could also be generated which sounds after the first sound has been switched off.

In the case of a container 1 with a reservoir 2 , a product discharge opening 3 and a device 4 for discharging product located in the reservoir 2 from the product discharge opening 3 , a noise generator 5 and a noise damper 13 are provided on the container 1 ( FIG. 19, FIG. 20). The sound generator 5 and the noise damper 13 are functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container 1 serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge 8 of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem 11 of the container 1 . The container 1 is an aerosol container. The spray channel leading to a nozzle 12 is provided in its cap 7 . A large number of individual channels 35 are provided as the noise damper 13 and the noise generator 5 .

Certain turbulences and thus corresponding frequencies occurring in a single spray channel are attenuated, as a result of which selective noise damping is achieved for this frequency range. The individual channels 35 thus act as a noise damper 13 . Noises that are typical for a large number of relatively narrow individual channels are amplified. The individual channels 35 act as a sound generator 5 . A modified, relatively pleasant sound is thus produced when the product in the container 1 is dispensed.

A known spray channel has a diameter of 2 mm and a length of 20 mm. The cross-sectional area is 3.141 mm ² . If, on the other hand, six individual channels 35 ( FIG. 20) are combined to form a bundle, each individual channel 35 having a diameter of 0.8 mm, the total flow diameter is 3.141 mm ² . Since the tube bundle can also better absorb the vibrations that occur, the following effects result: noise reduction, frequency change, and reduction in flow resistance and thus the eddies that occur, which leads to further noise reduction.

In a further exemplary embodiment ( FIGS. 21, 22 and 23), in the case of a container 1 with a reservoir 2 , a product discharge opening 3 and a device 4 for discharging product located in the reservoir 2 from the product discharge opening 3 on the container 1, a sound generator 5 and a Noise damper 13 provided. The noise generator 5 and the noise damper 13 are functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container 1 serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge 8 of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem 11 of the container 1 . The container 1 is an aerosol container. A spray channel leading to a nozzle 12 is provided in its cap 7 . A labium 36 is provided in the spray channel 10 as the noise damper 13 and the noise generator 5 . The labium 36 is a noise generator 5 and, together with the vertically oriented part of the spray channel 10, acts in a similar way to an organ pipe when the aerosol flows around it from the container 1 . At the same time, it acts as a selective noise damper 13 , since other frequencies that otherwise occur are suppressed or avoided by its presence.

In the embodiments of FIGS. 24 and 25 of an aerosol container is provided as a noise damper 13, a valve plate 38 at a damping valve plate 37. The valve plate damping 38 is a layer of a sound-absorbing material applied to the valve plate 37 . This material is on the one hand a polyurethane lacquer 39 ( FIG. 24) and on the other hand a polyurethane foam 40 ( FIG. 25).

The valve plate 37 is sealed against an upper edge of an aerosol container by a circumferential seal 41 . When removing the product from the aerosol container, e.g. B. by manual actuation of a spray head, the frequencies emitted by the valve plate 37 are damped by the valve plate damping 38 . It is such. B. produces a relatively pleasant spray noise. Similarly, a foam dispensing sound can also be changed. The aerosol container then has a foam generator at its product discharge opening.

In the case of a cap 7 for a container, a product discharge opening 3 and a device 4 for discharging product from the product discharge opening 3 are provided ( FIG. 26). A noise damper 13 is functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge of the container. A recess 9 at the lower end of a spray channel 10 receives a stem of the container. The container is an aerosol container. The spray channel 10 leading to a nozzle 12 is provided in its cap 7 . As a noise damper 13 , better than technology for preventing excessive noise generation, an insert 42 having a nozzle 12 is provided at the outflow end of the spray channel 10 , which insert 42 is made of an elastic plastic and thus acts as a noise damper 13 .

The escaping aerosol flows through the spray channel 10 and is sprayed out of the nozzle 12 . Due to the effect of the noise damper 13 , a relatively quiet noise, which is felt as very pleasant due to the selective damping in the plastic, is generated when the device 4 is actuated.

In the exemplary embodiment in FIG. 27, a noise generator 5 is provided on a container 1 with a reservoir 2 , a product discharge opening 3 and a device 4 for discharging product located in the reservoir 2 from the product discharge opening 3 . The sound generator 5 is functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container 1 serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge 8 of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem 11 of the container 1 . The container 1 is an aerosol container. The spray channel 10 leading to a nozzle 12 is provided in its cap 7 .

A horizontal, disk-shaped resonance surface 43 , which is oriented radially away from the spray channel 10 , is provided on the spray channel 10 as the noise generator 5 . If the button 6 is actuated, the spray channel 10 together with the stem 11 is pressed down and a valve (not shown) in the container 1 is actuated. The aerosol exiting through the stem 11 flows through the spray channel 10 and is sprayed out of the nozzle 12 . Due to the effect of the noise generator 5 , a sound that is predetermined as a result of the resonances of the resonance surface 43 and is felt as very pleasant is generated when the device 4 is actuated. The resonance surface 43 is rigidly connected to the inner wall of the cap 7 . The resonance surface 43 is a disk made of plastic.

In the exemplary embodiment of FIGS. 28 and 29 and in the exemplary embodiment of FIGS. 30 and 31, a technique for changing the sound corresponding to the exemplary embodiment of FIG. 27 is used. In the embodiment of FIGS. 28 and 29, two resonance surfaces 43 which run parallel to one another and run vertically are provided in the interior of a cap 7 , while in the embodiment of FIGS. 30 and 31 an annular resonance surface 43 is provided in a cap 7 . Depending on the arrangement in the cap 7 , the number of resonance surfaces 43 , the choice of material, the surface dimension and any connection to the cap 7 that is present, a corresponding sound can be achieved when a product is dispensed.

In the exemplary embodiment in FIG. 32, a container (not shown) is an aerosol container which has a valve 44 , a valve plate 37 , a valve housing 45 and a stem 11 . An acoustic barrier layer 46 is provided between the valve 44 and the valve plate 37 as the noise damper 13 . A part 47 of the barrier layer 46 is provided as a seal between the valve housing 45 and the stem 11 . In this way, the valve plate 37 and the valve housing 45 are acoustically decoupled from the valve 44 , which leads to damping of the vibrations otherwise transmitted from the valve 44 to the valve plate 37 and thus further to the container. Product delivery is perceived as quieter and more pleasant.

In the exemplary embodiment in FIG. 33, this is the case in an analogous manner; in contrast to the object in FIG. 32, however, a separate seal 48 is provided here between the stem 11 and the valve housing 45 in order to achieve an optimal sealing there.

In the embodiment of FIGS. 34, 35 and 36, a silencer 13 is provided in a container 1 with a reservoir 2 , a product discharge opening 3 and a device 4 for discharging product located in the reservoir 2 from the product discharge opening 3 . The noise damper 13 is functionally connected to the device 4 in order to generate a target sound for a product outflow during the product delivery.

A button 6 in a cap 7 of the container 1 serves as the device 4 for the discharge. The cap 7 can be plugged onto an edge 8 of the container 1 . A recess 9 at the lower end of a spray channel 10 receives a stem 11 of the container 1 . The container 1 is an aerosol container. The spray channel 10 leading to a nozzle 12 is provided in its cap 7 . An acoustic seal 49 between the button 6 and the cap 7 serves as the noise damper 13 . The seal 49 is made by two sealing lips 50, 51, in each case one sealing lip 51 on the cap 7 and another sealing lip 50 is provided on the key 6 (Fig. 34, Fig. 35). Even when the button 6 ( FIG. 36) is pressed down, the sealing lips remain in contact with one another and thus seal the interior of the cap 7 from the outside.

In the embodiment of Fig. 37, 38 and 39, the seal 49 by an elastic connection 52 between the button 6 and which adjoins the edge 53 of the key 6 the edge region 54 of the cap 7 is formed. Even after the button 6 ( FIG. 39) is pressed down, the seal is retained as a result of an expansion of the elastic connection 52 . If button 6 is actuated, a spray channel together with a stem (not shown) is pressed down and a valve (not shown) in the container is actuated. The aerosol emerging from the stem flows through the spray channel and is sprayed out of a nozzle. Due to the action of the noise damper 13 , a relatively quiet noise, which is also perceived as very pleasant due to the resonances in the cap 7 , is generated when the device 4 is actuated.

In the embodiment of Fig. 40 is provided as a sound generator 5 for a frequency range and a noise damper 13 for a different frequency range a perforated disc 55 inserted in a stem 11 having a plurality of channels 57, and which is preferably latched by a latching element 56 in the stem . If an aerosol is dispensed, it flows through channels 57 . A laminar flow is present in the channels 57 , which still occurs in part behind the perforated disk 55 . The result of this turbulence reduction is that individual frequencies are reduced in terms of their sound intensity and other frequencies are amplified. Overall, there is a change in frequency, which leads to a new sound. This sound depends on the number and length of the channels 57 and is generally perceived as relatively pleasant.

In the exemplary embodiment in FIGS . 41 to 43, the perforated disk 55 has channels 57 only on one side, a cover 58 , which is designed in the form of a half disk, partially covering the perforated disk 55 , which has an anti-rotation device 61 , and the cover 58 via a tube piece inserted into the stem 11 59 , which has a stop 60 and which is connected to a product delivery opening (not shown) of the container, is rotatable relative to the perforated disk 55 . In the state shown in FIGS. 41 and 42, the cover 58 covers a passage 62 , during which the channels 57 are free. An aerosol product thus flows through the channels 57 and generates a special noise, with which the perforated disk 55 acts as a noise generator 5 . Another noise, which comes from various turbulences, is reduced as a result of the laminar flow that occurs in the channels 57 . The perforated disk 55 thus also serves as a noise damper 13 . By rotating the pipe section 59 through 180 degrees, the cover 58 is brought over the channels 58 ( FIG. 43). As a result, the passage 62 is free. In this twisting situation, a different sound is obtained when the aerosol flows out, combined with a different, stronger flow. The stop 60 comes into operation in the case of a certain twisting situation and is correlated with a certain pivoting position of a product delivery opening which is provided at the upper end of the pipe section 59 in such a way that a consumer is informed of a certain outflow behavior depending on the pivoting position. Instead of a passage 62 , the perforated disk 55 could also have a disk material that is continuous there. Then you would determine by turning the pipe section 59 , how many of the channels 57 are used.

In the exemplary embodiment in FIGS . 44 and 45, a sound lip 64 is provided as the sound generator 5 in a flow channel 63 of an aerosol container. This is integrally connected to the lower part of a valve housing 45 . In this way, a certain tone can be generated by a product delivery. The sound lip 64 is set into vibration by the flowing product. Through the connection to the valve housing 45 , the sound lip 64 can be manufactured in a simple manner together with the valve housing 45 . In the case of the proposed arrangement of the sound lip on the lower part of the valve housing 45 , the product is liquid, so that there is no gluing and thus a restriction of the function of the sound lip 64 . A spray head (not shown) of the aerosol container, which is pressed downward in order to open a valve 44, serves as the device for the discharge. The product flows around the sound lip 64 and up through the valve 44 and produces a sound which is perceived as pleasant during the product delivery on the sound lip 64 . The sound lip 64 is aligned in the direction of the flow channel 63 . The outflowing product has a relatively large flow section available so that the outflow is virtually unaffected. The length of the sound lip 64 is designed for a resonance of a certain frequency and its overtones. Instead of downwards, the sound lip 64 can also point upwards ( FIG. 46, FIG. 47).

In the embodiment of FIGS. 48, 49 and 50, two sound lips 64 are provided, which are aligned perpendicular to the direction of the flow channel 63 and in such a way that they form a gap 65 between them. In this way, a relatively intense tone can be produced. Alternatively, the sound lips 65 can also overlap (FIGS . 51, 52 and 53), which can lead to an even higher sound intensity. In these two exemplary embodiments, a relatively narrow passage is created in the flow channel 63 , through which the product must flow. On the one hand, the passage through the gap 65 ( FIG. 49) is given, on the other hand by the sound lips arranged one above the other being pivoted upwards and pressed away from one another ( FIG. 52). Recesses 67 on the edge of the sound lips 65 ( FIG. 53) allow the sound lips 65 to pivot in the flow channel 63 . The product portion flowing through the recesses 67 produces a further tone there. There is therefore a noise which depends on the one hand on the vibration of the sound lips 65 and their distance from one another, and on the other hand on the size of the cutouts 67 . This sound is felt to be relatively pleasant.

A vertical sound lip 64 as a sound generator 5 ( Fig. 44) z. B. can be used for hairspray, which causes a normal hold of the hair. In contrast, sound lips 64 of FIGS . 49 and 52 can be used as sound generators 5 in hairspray for strong and extra strong hold. A consumer is thus signaled on the basis of the sound of the product delivery noise, what kind of hair spray is being sprayed out.

In the exemplary embodiment in FIGS. 54 to 57, a very special whistling sound is generated during the dispensing of product from an aerosol container. For this purpose, a passage 68 of a blocking element 69 is provided in the flow direction in front of the sound lip 64 , and an edge 70 of the sound lip 64 forms a labial pipe 71 with the passage 68 . The labial pipe 71 is formed in that the edge 70 is relatively close to the passage 68 . The frequency of the sound to be generated can be changed by changing the gap width of the passage 68 or the distance of the edge 70 from the passage 68 . The tone is adjusted in such a way that it is perceived as pleasant by a consumer during a product delivery. The relationships shown in FIGS. 54 to 57 lead to a relatively rich tone in the middle frequency range. The sound lip 64 could additionally have a gap that completely divides it from top to bottom. Then a second tone would be superimposed on the first tone, which would lead to a further, relatively pleasant sound image.

In the exemplary embodiment in FIGS. 58 and 59, a plurality of grooves 73 which delimit the flow channel 63 and extend in the flow direction are provided at the same time as the noise damper 13 and as the noise generator 5 . The flow channel 63 serves for an outflow of aerosol product through the flow channel 63 when the stem 11 of the valve 44 of the aerosol container is tilted. Recesses are formed as grooves 73 in an extension 72 of a valve housing 45 of a valve 44 . The turbulence in this area of the flow channel 63 can thus be reduced. By eliminating these turbulences, the frequencies that are generated by these turbulences of the outflowing aerosol product are damped. At the same time, the grooves 73 produce a different tone. This change in frequency is perceived as relatively pleasant. The corresponding sound is influenced by the length, width and depth of the grooves 73 , as well as by the number of grooves 73 . The grooves 73 could also sit a little higher, and be provided inside the riser 66 or inside the stem 11 . They always serve the same purpose, but depending on their exact location, they always have a different effect on the sound during product delivery.

In the embodiment of FIG. 60, a funnel-shaped loudspeaker 74 is provided both as a sound generator 5 and as a noise damper 13 , which connects to a product delivery opening 3 of the container 1 designed as a nozzle 12 . The loudspeaker 74 has an increasing diameter when viewed away from the nozzle 12 . Like a speaking bag, the sound is changed and amplified at the same time as a product is being delivered. The spray cone emitted by the nozzle 12 has sufficient free space in the loudspeaker 74 . The attachment 75 is placed with its recess 9 on the stem 11 of the container 11 . If you then press the attachment 75 downward, an aerosol 08691 00070 552 001000280000000200012000285910858000040 0002010125958 00004 08572 flows out through the stem 11 , the spray channel 10 , the nozzle 12 and the loudspeaker 74 and produces a pleasant feeling in the loudspeaker 74 by frequency shift and sound amplification Sound. The attachment 75 serves here as a device 4 for discharging.

In the embodiment of FIG. 61, a button 6 of a cap 7 that can be placed on a container 1 is provided as the device 4 for discharging. The button 6 acts mechanically on the wall 15 of the spray channel 10 . The wall 15 in turn acts mechanically on a stem 11 of the container 1 . When the button 6 is pressed down, a valve (not shown) located below the stem 11 is opened such that product is sprayed out through the spray channel 10 and a nozzle 12 . A loudspeaker 74 serves as noise damper 13 and noise generator 5 , just as in the exemplary embodiment in FIG. 60.

In the embodiment of FIGS. 65 to 67, a sound rib 16 is provided as the sound generator 5 , which is connected on the one hand to an attachment 75 which is plugged onto a stem 11 of a container 1 filled with aerosol, and on the other hand rests against an edge of the container 1 . The sound rib 16 engages under the edge 8 by means of a bead 76 and is thus arranged in a relatively rigid manner. A tear-off element 78 can be bent at a weakening line 79 and separated from the attachment 75 in this way. In this way, a user can either generate a simple or a modified sound with or without a tear-off element.

In the exemplary embodiment of FIGS . 65 to 67, a tear-off ring 77 which engages under the edge 8 of the container is provided in a modified manner on the container 1 and is connected to two sound ribs 16 via a weakening line 79 . First, the tear-off ring 77 provided for transport reasons is removed by destroying the weakening line 79 . Then press on the top 75 , which acts as a device 4 for discharge. The product emerging through the stem 11 , the spray channel 10 and the nozzle 12 produces a sound which excites the two unequal-sized sound ribs 16 to vibrate ( FIG. 66). This creates a two-tone that is perceived as pleasant.

In the embodiment of Fig. 68 to 70 is provided as a sound generator 5 for an aerosol container designed as a channel flow loop. The flow loop 80 is located in the valve body 81 of the valve 44 . By tilting the stem 11 , the valve 44 is opened and an aerosol product flows out through the flow channel 63 . As a result of flow turbulence before entry into the stem 11 , a relatively small proportion of the product flow enters the flow loop 80 and generates a resonance oscillation there. The information to be at the entrances into the flow loop 80 expansion of the liquid propellant to its gaseous phase is transferred in terms of pressure in the flow loop 80, and so generates an additional sound while a product dispensing.

In the exemplary embodiments of FIGS. 71 and 72, an aerosol container is provided as container 1 , which has an ascending pipe 66 leading to a valve 44 . The riser pipe 66 has an extension 82 as the sound generator 5 . The extension 82 lies either only against the bottom wall 83 ( FIG. 72) or against both the bottom wall 83 and the side wall 84 of the container ( FIG. 71). For example, the flow noise of the aerosol in the riser 66 is amplified in the extension 82 . On the other hand, this amplified noise is transmitted to a container wall so that it is used as a resonator. The sound achieved is therefore dependent on the dimensions of the walls and, especially with aluminum cans, results in a somewhat deeper, relatively pleasant sound during product delivery. In the exemplary embodiment in FIG. 71, as a result of the two transmission points for the riser pipe 66, there is an amplitude shift between a standing wave in the side wall on the one hand and a standing wave in the bottom wall on the other hand. This also advantageously changes the sound pattern.

In the exemplary embodiment in FIG. 73, the container 1 is an aerosol container, the bottom wall 83 of which as the noise generator 5 alternately has a larger wall thickness 86 and a smaller wall thickness 85 . In this way, the bottom wall 83 effects a changed sound image during product delivery.

In accordance with the difference in thickness and the dimensions of the larger wall thickness 86 , an aerosol dispensing noise which is perceived as pleasant can be achieved. As an alternative to this, the side wall 84 could be configured analogously to the bottom wall 83 , or a wall could be designed in a wavy line with a constant wall thickness. 1 container
